Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional brassieres are not suitable for backless dresses as they often require painful adhesives or visible straps, failing to provide comfort, support, and aesthetics.

Innovation Solution

A brassiere design featuring straps that wrap around the shoulders, with cups and straps connected via a support portion, allowing the straps to be discreetly positioned and providing support without visible attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional brassieres are used for backless dresses, then support function is provided, but the straps are visible or adhesive is needed on skin

Engineering Contradiction:

Improvecomfort and aestheticsVSAvoidstrap configuration

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent moves the strap attachment point from the traditional back or front to the shoulder dimension. The straps wrap around the shoulders from front to back, utilizing the vertical and circumferential dimensions of the shoulder to achieve hidden support without visible adhesive on the back or front.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The shoulder acts as an intermediary structure between the cup and the backless dress. By routing straps through the shoulder contour, the invention creates a hidden support mechanism that avoids direct skin adhesion on visible areas while maintaining structural support.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If adhesive solutions are used to create backless effect, then strap visibility is eliminated, but skin comfort deteriorates due to painful adhesives

Engineering Contradiction:

ImproveaestheticsVSAvoidskin discomfort

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The invention extracts the adhesive element entirely from the brassiere design. Instead of using adhesive to attach straps to the back or front, the straps are routed over the shoulder contour, eliminating the need for skin-contact adhesives and their associated discomfort.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The invention converts the potentially harmful adhesive-skin contact into a beneficial mechanical routing system. The shoulder structure, which naturally supports weight, is utilized to bear the brassiere load without requiring adhesive, transforming a problematic attachment method into an ergonomic solution.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Strength

If traditional brassiere straps are used, then support is provided, but the straps are visible on the back

Engineering Contradiction:

ImprovesupportVSAvoidaesthetics

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The patent employs asymmetric strap routing where the straps wrap around the shoulders in a non-traditional pattern. Instead of straight back straps, they follow the shoulder contour and cross asymmetrically, hiding the strap mechanism from rear view while maintaining support distribution.

Inventive Principle:

Principle #4Asymmetry

Solution Approach 2:

The invention inverts the traditional strap direction by having straps originate from the front cups and wrap around the shoulders to the back, rather than attaching at the back and extending forward. This reversal hides the strap attachment points from the back view while preserving support function.

Inventive Principle:

Principle #13The other way round (Inversion)
